Ask It: 2010 Roush 540RH

As if the too-hot Roush 427R wasn't enough, the much-loved tuning company has now put another spin on the 2010 Mustang. Appearance-wise, this one is much more tame and subtle than some of the cleft-chinned 'Stangs we've driven, but don't let its looks fool you. The supercharger under this Mustang's hood bumps up power to a GT500-matching 540 ponies, and with suspension tweaking on hand, this latest Roush will surely be a hit for Mustang enthusiasts.

Since we'll be testing the car for the next week, post whatever questions you have about the 540RH and we'll do our best to respond. Check back for driving impressions and other logbook comments, too.
